摘　　要：在对光伏阵列输出特性分析的基础上,综合了传统的最大功率点跟踪(MPPT)控制算法的优点,提出了一种将固定电流法、固定电压法和增量电导法相结合的MPPT控制算法,使用Matlab/Simulink对该控制算法与增量电导法进行了仿真比较。仿真结果表明该算法有效地提高了系统MPPT控制的响应速度和精度,并且具有较强的抗干扰能力,能够更好地适应外界环境变化。On the basis of the analysis of the output characteristic of photovoltaic array, an improved maximum power point tracking（MPPT） control algorithm combining incremental conductance algorithm with constant voltage algorithm and constant current algorithm was proposed by integrating the advantages of traditional MPPT control algorithms.The proposed algorithm and incremental conductance algorithms were simulated with Matlab/Simulink program.The simulation results showed that the proposed scheme could greatly improve the MPPT response speed and accuracy.Moreover, it was more suitable for operating condition change due to the strong capability of anti-interference.
